What is a conditioned secondary reinforcer?

• A. The clicker or marker word
• B. A primary reinforcer
• C. A punishment cue
• D. A neutral stimulus with no reward history

Answer: (A)

A conditioned secondary reinforcer is a stimulus that gains reinforcing value by being paired with a primary reinforcer. In dog training, the clicker or marker word is a classic example: it starts out neutral, but after it’s consistently followed by a primary reward (like a treat), the dog learns to associate the click with that reward. The click then becomes reinforcing in its own right, signaling “reward is coming now,” which strengthens the desired behavior. This differs from a primary reinforcer, which satisfies a basic biological need directly, and from a punishment cue, which aims to decrease behavior. A neutral stimulus with no reward history wouldn’t reinforce, because it hasn’t acquired that learned association. So the clicker or marker word best fits as a conditioned secondary reinforcer.
